Hmm...an interesting idea but not one of the better episodes.
6 May 2010 | by (Bradenton, Florida) – See all my reviews

I recently purchased the "UFO" box set and have been watching the shows. While, of course, the special effects and costumes are pretty campy, the plots have been excellent--and I have so far enjoyed the show far more than I'd expected. However, episode 1.10 is clearly not one of the better shows--even if the idea is pretty good.

A man and an older woman are lovers and planning on murdering her husband. At the same time, a UFO lands and the alien is walking about the countryside. While the lady is waiting for her husband to return home so she can 'accidentally' shoot him, she ends up shooting the alien instead, as he tries to break in to the home and she thinks it's the hubby. SHADO soon finds out that this occurred and they take the woman and her lover into custody to debrief them and administer an amnesia drug--making them forget the last 12 hours. However, in the process of interviewing these two would-be criminals, they learn of their murder plot. How this interesting idea was solved was a HUGE disappointment--and surely there must have been some better way to handle this (as evidenced in the final scene). All in all, because of this awful ending, I felt very unsatisfied by the whole thing and can't believe they let this good idea go to waste.
